pagination object in the request body. It is optional — omit it and you get page 1 with 50 records.
Paginated responses return
pagination next to result, not inside it.
POST /transactions always returns total_records and total_pages as null. Call POST /transactions/count with the same filter body to get the totals — the two requests are designed to run in parallel./transactions, /transactions/count, and /transactions/summary.
